Eyelight Plays with Depth of Field - Part 7: DOF Based on View Size

This comparison uses the same aperture (f/11) and same subject/view size (16.78”) with four different focal lengths.

• The red line represents the width of the subject/view.
• Positions a, b, c and d represent camera positions using the four focal lengths in the table.
• Black lines represent angle of view for each focal length.
• Distance for each calculated using cad software.
• Depth of field info calculated using Photo Caddie.

A picture (diagram) is worth a thousand words the saying goes.

Very interesting. Wouldn't have thought the DOF would have been that close together. Where did you get your information from.

The idea came form reading an article on CiC, Understanding Depth of Field in Photography

The diagram and table I created using cad software and DOF calculator.
